This document presents the position of OICA working groups on
WLTP mode construction. The proposal covers mode construction for conventional vehicles with options to be tested in Validation 2, including for electrified vehicles.

Summary of the 8th meeting of the informal group developing the test procedures for the WLTP GTR.

Revised proposal to support development of the WLTP test procedures.

Agenda for the ninth session of the informal group working on the test procedures for the worldwide light vehicle emissions test procedure.

Paper intended to explore the inclusion of vehicle families in the WLTP GTR. In principle, global technical regulations (GTR) are restricted to technical issues such as test cycles and procedures and do not include definitions of families.

Status of the work on drafing the global technical regulation on light vehicle emissions test procedures.

Project schedule for the development, validation, and finalization of the global technical regulation on light vehicle emissions testing by the end of 2012.

Presentation on the combined approach for vehicle test weight, stepless inertia and vehicle selection developed by RDW, ICCT, and T&E.

Explanation of the proposal from RDW, T&E and ICCT for an improved definition of vehicle test mass as well as the proposal from ICCT to substitute the current step-based inertia class system by a step-less approach.

Review of the program for validation of both the new WLTP test cycle and the new WLTP test procedure towards producing a final evaluation report.

ACEA review of issues requiring resolution pursuant to the phase 2 validation of the WLTP test procedures.

Current draft annex prepared by the WLTP subgroup developing guidelines for reference fuels to be used in the light vehicle emissions test procedures.

Progress report of the WLTP subgroup working on the test procedures for measuring emissions of pollutants not covered by other subgroups (NO2, N2O, NH3, etc.).

Progress report of the WLTP subgroup working on test procedures for particulate measurement.

Progress report of the WLTP subgroup working on lab procedures for testing of electric vehicles.

Progress report of the WLTP subgroup working on lab procedures for testing of internal combustion engines.

Summary of the ninth meeting of the informal subgroup of WLTP working on the development of the test procedures.

Organizational remarks and overview of the status of work of the informal subgroup working on development of the test procedures for the WLTP going into its ninth session.

In 2011, the WLTP-DTP group agreed to pursue an improved definition of vehicle test mass and a step-less approach to the inertia class system. This revised document describes the current view on the combined approach for vehicle test mass, inertia setting, tire and vehicle selection.

WLTP GTR Drafting Coordinator draft version of the regulation, uploaded on the CIRCA website, as referenced in WLTP-DTP-10 meeting notes.

Review of the 10th WLTP-DTP subgroup meeting discussions and remaining open items.

Where things stand in the development of the text of the WLTP GTR.

MS Excel download summary of the most relevant parameters identified by the DTP subgroup on Lab Procedures for Internal Combustion Engines (LabProcICE).

Information on the testing programs to be completed no later than September 2012.

44-page review of the WLTP assessment criteria as developed by the DTP subgroups on Lab Procedures for ICE, Particulate Measurement/Particle Numbers, Additional Pollutants, and Electric Vehicles.

Review of the program for the second phase of validations of the proposed WLTP test procedures.
